- 新页面userbase.html,用<ul ><li role="presentation"> 实现标签页导航。
<ul class="nav nav-tabs">
<li role="presentation"><a href="#">Home</a></li>
<li role="presentation"><a href="#">Profile</a></li>
<li role="presentation"><a href="#">Messages</a></li>
</ul>
<ul class="nav_ul"> <li role="presentation"><a herf="#">Questions</a></li> <li role="presentation"><a herf="#">Comments</a></li> <li role="presentation"><a herf="#">Information</a></li> </ul>
- 让userbase.html继承base.html。
重写title,head,main块.
将上述<ul>的样式放在head块，<ul>放在main块中.
定义新的块user。{% extends‘base.html‘ %} {% block title %}个人中心{% endblock %} {% block head %} <style> .nav_ul li{ list-style: none; float:left; margin:10px; } </style> {% endblock %} {% block main %} <ul class="nav_ul"> <li role="presentation"><a herf="#">Questions</a></li> <li role="presentation"><a herf="#">Comments</a></li> <li role="presentation"><a herf="#">Information</a></li> </ul> {% block user %}{% endblock %} {% endblock %} - 让上次作业完成的个人中心页面，继承userbase.html，原个人中心就自动有了标签页导航。
{% extends ‘userbase.html‘ %} {% block title %}个人中心{% endblock %} {% block main %} <div class="page-header"> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span> {{ username }}<br><small>全部问答<span class="badge"></span> </small></h3> <ul class="list-group" style="..."> {% for foo in questions %} <li class="list-group-item"> <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span> <a herf="#">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span> <p style="...">{{ foo.detail }}</p> </li> {% endfor %} </ul> </div> <div class="page-header"...> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span> {{ username }}<br><small>全部评论<span class="badge"></span> </small></h3> <ul class="list-group" style="..."> {% for foo in questions %} <li class="list-group-item"> <span class="glyphicon glyphicon-heart-empty" aria-hidden="true"></span> <a herf="#">{{ foo.author.username }}</a> <span class="badge">{{ foo.creat_time }}</span> <p style="...">{{ foo.detail }}</p> </li> {% endfor %} </ul> </div> <div class="page-header"...> <h3><span class="glyphicon glyphicon-user" aria-hidden="true"></span> {{ username }}<br><small>全部评论<span class="badge"></span> </small></h3> <ul class="list-group" style="..."> <li class="list-group-item">用户：{{ username }}</li> <li class="list-group-item">编号：</li> <li class="list-group-item">昵称：</li> <li class="list-group-item">文章篇数：</li> </ul> </div> {% endblock %} - 制作个人中心的三个子页面，重写userbase.html中定义的user块，分别用于显示问答、评论、个人信息。
{% extends ‘usercenter.html‘ %} {% block user %} <div class="page-header"> <span class="glyphicon glyphicon-info-sign" aria-hidden="true">全部问答</span> <ul class="list-group"></ul> </div> {% endblock %}{% extends ‘usercenter.html‘ %} {% block user %} <div class="page-header"> <span class="glyphicon glyphicon-info-sign" aria-hidden="true">全部评论</span> <ul class="list-group"></ul> </div> {% endblock %}{% extends ‘usercenter.html‘ %} {% block user %} <div class="page-header"> <span class="glyphicon glyphicon-info-sign" aria-hidden="true">个人信息</span> <ul class="list-group"></ul> </div> {% endblock %} - 思考 如何实现点标签页导航到达不同的个人中心子页面。
<li role="presentation"><a href="{{url_for(‘usercenter‘,user_id=user.id,tag=‘1‘)}}">全部问答</a></li> <li role="presentation"><a href="{{url_for(‘usercenter‘,user_id=user.id,tag=‘2‘)}}">全部评论</a></li> <li role="presentation"><a href="{{url_for(‘usercenter‘,user_id=user.id,tag=‘3‘)}}">个人信息</a></li>
<a href="{{url_for(‘usercenter‘,user_id=ques.author_id,tag=1)}}">{{foo.author.username}}</a>
